Parking place obstruction

ABSTRACT

Theft preventing means at a parking lot comprising a hindrance means (10, 30) raisable from a retired position and lockable in a raised position. The hindrance means comprises a tubular part (10) depressed into the ground at the parking lot, and a post (30) telescopically mounted therein. The post (30) has a slot (40) in which a catch (41) is pivotally mounted between an inner position, in which the catch is accommodated within the cross section of the post and an outer position in which the post is prevented from being pushed down in part (10), on the post. An opening (44) is arranged in the catch (41) for receiving the clamp of a padlock.

The invention refers to a means according to the preamble of claim 1.

Means of this kind are well known in many embodiments, and are usedpartly for making it more difficult to or prevent the driving of a carpast the raised hindrance means, and partly to prevent unauthorizedparking in the parking lot.

One important problem has been the manufacturing of a raisable/removablehindrance means, which is robust, can be manufactured at a low cost, iseasy to manipulate and also can be used at extreme weather conditions asin snowy and cold weather.

The object of the invention is accomplished by the means according tothe invention as defined in the characterizing part of claim 1.

Embodiments of the invention will be evident from the subclaims and arefurther described below with reference to the accompanying drawing.

In the drawing, the FIGURE shows an axial, partly cross-sectional viewof a hindrance means according to the invention.

The surface of the ground is identified with the reference numeral 400.

A tubular part (10) is mounted in the ground.

Part 10 comprises a sleeve 11 with bottom 13 and a radially projectingbottom flange 14 and a radially projecting upper edge flange 12. Theflange 12 comprises a collar 100 which is connected to the sleeve 11.

The flange 12 has a seam 15. In this seam a hindrance means 16 isimmersed, which reaches down in the sleeve 11. This hindrance means 16is turned with a stepped form 17. The hindrance means 16 is connected tothe flange 12 through a screw joint 18.

In the seam 15, on top of the hindrance means 16, is mounted a packingbox 200.

A packing flange 19 has a seam 20, in which seam a scraper ring 300 isarranged, and underneath the scraper ring a washer 21 is mounted, whichholds the scraper ring 300 in place.

The flanges 12,19 are connected to each other through a screw joint 22.

A post 30 made of solid material passes with a slip fit through thepacking box 200 and the scraper ring 300 down into the sleeve 11 havinga larger inside diameter than the post 30.

A cylindrical guide body 31 is arranged having an outside diametercorresponding to the inner diameter of the sleeve 11 and preventsremoval of the post 30 from part 10 by abutting the hindrance means 16.

The sleeve 11 is deep enough for inserting the post therein, whereby thecap 70 on the post will rest on the flange 19 and/or the surface of theground 400.

The cap 70 can be convex on the upper side and be provided with alifting means 71, such as a pulling ring, which is immersed in a groovein the cap 70, which pulling ring is provided with a holder acting as ahinge.

The post 30 has an axial slot 40 and a catch 41, which through a groove42 in the catch 41 is guided by a pin 43, which prevents the catch 41from sliding completely out of the slot 40.

The catch is retractable into the slot 40 to an inner position, where itis accomodated inside the outer diameter of the post, and it isextendable by its own weight. When the catch 41 has passed the upperpart of the scraping ring 300/the surface of the ground 400, the catchfalls out under its own weight and rests on the packing flange 19 andthe surface of the ground 400, whereby the opening 44 is exposed. Apadlock is mounted with its clamp through the opening 44 and preventsdepression of the post 30 into the sleeve 10.

The embodiment shown in the drawing has proved to fullfill all practicaldemands put on a hindrance means, and thereby eliminates alldisadvantages and defects associated with previously known embodimentsof hindrance means.

I claim:
 1. A means at a parking lot having at its front end a barrierand, at its back end, a hindrance means (10,30) which is raisable from aretired position and which is lockable in a raised position, whereby thehindrance means (10,30) comprises a tubular part, which is recessedlymounted in the ground at the parking lot, and a post (30), which istelescopically mounted in said tubular part, which post is connected toa guide body (31) preventing the post (30) from being dragged out of asleeve (11) by a second hindrance means (16), characterized in that thepost (30) comprises a slot (40) wherein a catch (41) is pivotallymounted on the post between an inner position, wherein the catch lieswithin the cross section of the post, and an outer position in which thecatch (41) projects outside said cross section and prevents the postfrom being pushed down from its raised, locked position, and in that anopening (44) is arranged in the projecting part of the catch (41) inorder to receive a padlock clamp.
 2. Means according to claim 1,characterized in that the slot (40) is arranged substantially axially inthe, preferably solid post (30).
